Measuring synthesis yield in graphene oxide synthesis by modified hummers method

Abstract

Synthesis of graphene oxide by the modified Hummers method and measuring the synthesis yield were investigated. Based on the results, a comprehensive method to measure graphene oxide synthesis yield was proposed, which will allow comparison of future literature results. In addition, changes are proposed to the exfoliation procedure to improve the yield of the modified Hummers synthesis. With the proposed method, systematic error of the concentration measurement was calculated to be ±0.08 × 10^-3 g mL^-1. In addition, changes proposed to the graphene oxide exfoliation process can improve the synthesis yield by up to 70%.
